Be it known that I, ROBERT J. lifl lloiNAv Ir, residing atl'Voodla'vvn, in' the' county ot Beavei',"a'n ;l` State' of 'Pennsylvania, a citizen oit themUnited" States,haveinvented or 'discovered certain "newy and useful Tm'- Ipro've'nients"in wWater Closets; of "Which "in 'ip"roveinerits the tolloivings'a specification.l

substantially so, at the upper rim-aiidroin thefrearjand" affords :af suitable passage vthrough which I accomplish the desired ventilation. It will of course "he under- StoodA that another passageway might loe provided.

The Ventilating pipe 5 as here arranged leads from a horizontal reach of flushing; pipe 4f, and leads vertically downward, and,

as will he understood, leads to suitable place of gas delivery. The particular positions, relative to the vertical, here noted are -not essential, hut are convenient,

Communication from flushing pipe 4. through ventilation pipe 5 is normally cut olil by valve 7, and accordingly a valve casing 8 is introduced at an intermediate point in the extent of flushing; pipe 4, and Within this casing valve 7 functions. Normally, as I r,is thus in service kep necessary nor after flushing,

Hthin pipe 5, beneath valve T, and conveniently adjacent valve '7, are arranged means for inducing a How of air from the howl through pipe 5. These means include essentially the nozzle 6 adapted to project a. jet of fluid into pipe 5 in direction such as to induce the desired iow downward, as here shown. The fluid employed may be such as desired, but conveniently it will he Water from the Water supply and under the head which obtains; and, accordingly, the nozzle 6 is here shown to be fed from the supply pipe 9 which leads also to tank 3. A control t, under' A spring valve in a suitable casing 10 stands normally closed, but at suitable time is opened to allow water underv pressure to iiow to nozzle 6 and to be projected from the nozzle in a' jet. The nozzle may in its minute construction be such as desired; I have indicated a nozzle including two relatively rotary mem@ bers-a familiar construction. By relative turning the orilice may be enlarged and vdiminished and modiiied in shape, to project a jet varyinginshape and in force.

The jet 6 is preferably arranged centrally within pipe 5, delivering its jet axially downward. advantageous to place within pipe 5 a Venturi tube 11, into which the jet is immediately projected. The presence of the Venturi tube increases the suction, or inductive elect.

Nozzle 6 may be carried on a bridge-12, and this bridge with its nozzle and pipe connection, together' with the Venturi-tube, may be madey up as an integral fitting, adapted to be 'introduced intermediately in the eX-.

tent of pipe 5, all as yclearly indicated in Figs. III and IV.

The air valve 7 in casing 8 and the water valve iii` casing 10, both stand normally closed. When both are open, the jet of water projected from nozzle y(5 induces 'a ventilat ing stream of air freni-the bowl through pipe v5.

The water closet seat 2 constitutes one end of a beam pivoted at 13; the opposite end of the beaingevtends` rearward at an arm 14. 15 engaging this beam holds it `normally in such position that the seat -is slightly i'aised, standing in such position as is indicated in Fig. I. When a user sits j 4o` upon the seat his weight overcomes the resistance of the spring and swings the beam (depressing the seat) through a slight but sufficient swing (anticlockwise upon pivot 13, asillustrated in Fig. I). The upward swing of arm 14 is suiiicient, through suitable connections sutliciently illustrated in thedrawings and requiring no minute` enumeration, to open both valves. The connections are advantageously so' adjusted that the valve within casing 10 opens first; so that Associated with 'the jet I find it the jet from nozzle 6 is already exerting its' lowing the two. valves to seat themselves again, preferably in inverse order-first valve 7, then the valve controlling the flow of water to nozzle 6.

v Operation may be briefly When the user seats himself, hisweight efsummarized ects automatic opening of the `two valves,

and so long through the proximate end of pipe 4,

j ectionable gases. When the user leaves the yseat the valves will close` and the pipe 4 will upon valve 7 normally dipsiand from which 1 it Vrises to open the pathway for the flow ot ythe Ventilating stream of air. v. j

- I claim as my invention:

Y In a water-closet installation the combination with a bowl kand a flushing pipe openrre.

ing horizontally thereto, a Ventilating opening vertically from the horizontal reach of the flushing pipe andsurrounded zat its as he remains seated a ventilat# ing stream of air will flow' from the bowl and thence through pipe 5 carrying with it obupper end with a water-receiving channel, i a valve with flanged .periphery adapted to move vertically labove ythe upper end of the Ventilating pipe and by flange into and rising out from a body of water maintained in said channel `alternately closing `and opening communication.

from vflushing pipe to' Ventilating pipe, means for raising said valve, and a fluidsupply pipe terminating in a nozzle within` the Ventilating pipe and at a point in the induced stream beyond said iianged valve.

In testimony whereof I have hereunto set my hand. l n i f i 'ROBERT J. MOLANAHAN.
